    摘要： An optical device includes a transparent substrate and a conductive layer disposed over an upper surface of the transparent substrate. The conductive layer defines at least one groove inwardly extending from an upper surface and includes an aperture that is spaced apart from the at least one groove. An interface between the upper surface of the conductive layer and an ambient medium defines an optical branch along which surface plasmon polariton modes are excited in response to at least partially coherent light being received by the optical device.

    摘要： The present invention provides a method of determining the amount of an optical probe species binding to or releasing from an optical sensor surface characterized in that the determination comprises the steps of: a) determining, at one single wavelength or at more than one wavelength, a physical measurand (xi) that is related to the absorptivity of said probe, b) correlating the value of the measurand to the amount of said optical probe species binding to or releasing from said surface, respectively, wherein the physical measurand (xi) of step a) is a physical measurand in which the contribution from the refractive index is substantially zero. The present invention further provides different uses of a peak width as well as a computer program product and reagent kits for the disclosed methods.
